Hi,what is the weather like in May and how many days do you think is suitable to spend in Shenzhen?

During THAT time, rainstorms, thunderstorms and typhoons are common there. The temperature is about 25~30C, but you may feel extremely hot because of the high humidity. Skirts, dresses, and shorts are proper for this time. A raincoat or umbrella is a must. Usually, 2 days are enough to spend there.
